Solaris iscsi targets with Mutlipath.

[awatkins1966]

Hello,

Wonder if any one has got iscsi targets working with multipath on Solaris 11?

First, I can access my iscsi targets from Solaris fine, but I would like to set up multipath so it works with failover VLANS. At the moment I think I am setting them up correctly, but failover does not work.

My steps:
# cp /kernel/drv/scsi_vhci.conf /etc/driver/drv/scsi_vhci.conf
# diff /kernel/drv/scsi_vhci.conf /etc/driver/drv/scsi_vhci.conf
76a77,79
> mpxio-disable="no";
> scsi-vhci-failover-override = "SCST_BIO", "f_sym";

# iscsiadm modify initiator-node -c 2

# iscsiadm add static-config iqn.2017-10.uk.ac.bbk:dss.solar1,10.63.10.220:3260
# iscsiadm add static-config iqn.2017-10.uk.ac.bbk:dss.solar1,10.63.11.220:3260

# format < /dev/null

/scsi_vhci/disk@g737a344870495842

So it seems to be working, but if I fail the first network it just hangs.

Any ideas?

Hi,

This seems to be a Solaris issue most probably.
However, you may try to use Windows machine to configure MPIO from this side and see if it works.
This should tell you if such an environment can work with MPIO at all.
